This work analyzes an interrelationship between stock indices S&P 500, FTSE 100, DAX, HSI, Nikkei, BSI and PX in a time period from September 2004 till March 2010. Such an interrelationship has already been examined and a dominating position of American indices has been found. This influence was stronger during a financial crisis. Because the examined time period covers both financial crisis and the period before, the work studies their interrelationship in the whole period and at the end in the time period before financial crisis. The influence of one stock index on the other can be cause by several factors: (i) dominance of influencing stock index, (ii) efficient market and (iii) financial crisis. As the reaction of stock index is evoked from new information, the intention of this work is to take into account nonsychronous trading of stocks exchanges. Therefore I explored those exchange stocks closing earlier than the others start in two ways by respecting the time lag and by non-respecting the time lag. The interrelationship between the indices was modeled with help of VAR models and proved by Granger causality test.

Ever since Ghana gained independence, its policy makers have identified education as a tool to foster economic growth and development. In recognition of the vast potential for national development that education presents Ghana, various governments have invested considerably in the sector. These investments have been in the form of educational sector reforms, as well as yearly reoccurring expenditure. Despite these massive investments however, very little work has been done to empirically investigate the impact of such expenditure on the nation’s economy. This paper uses data from Ghana to empirically assess the nature of the relationship between education expenditure (a proxy for human capital development) and GDP growth (a proxy for economic growth). The Granger Causality Test is applied to education expenditure and GDP growth data, from 2003 to 2018. Using data from this same time frame, separate Granger Causality tests are also implemented to test the relationship between Gross Enrollment Rates/ Total Completion Rates, at some levels of education, and GDP growth.   Interestingly enough, the analysis shows no Granger causal relationship between our main variables of interest (Total Education Expenditure and GDP growth). Results also show that none of the education variables Granger cause GDP growth, if the test uses 1 lag and also if the test uses 3 lags. Additionally, results show that whether the test uses 1 lag or 2 lags, GDP growth Granger causes the percentage of total government expenditure that is dedicated to education. Results for tests that use 2 lags also shows that the only education variable that Granger causes GDP growth is enrolment rate at the primary level, with GDP growth also not Granger causing any education variable apart from the percentage of government expenditure dedicated to education. In the case of the test using 3 lags, results show that GDP growth Granger causes only one education variable which is expenditure on the Senior High School level. / Ända sedan Ghana blev självständigt har dess beslutsfattare identifierat utbildning som ett verktyg för att främja ekonomisk tillväxt och utveckling. Som ett erkännande av den enorma potential för nationell utveckling som utbildning erbjuder Ghana, har olika regeringar investerat avsevärt i sektorn. Dessa investeringar har varit i form av reformer av utbildningssektorn, såväl som årliga återkommande utgifter. Trots dessa massiva investeringar har dock mycket lite arbete gjorts för att empiriskt undersöka effekterna av sådana utgifter på landets ekonomi. Denna artikel använder data från Ghana för att empiriskt bedöma karaktären av sambandet mellan utbildningsutgifter (en proxy för utveckling av mänskligt kapital) och BNP-tillväxt (en proxy för ekonomisk tillväxt). Granger Causality Test tillämpas på utbildningsutgifter och BNP-tillväxtdata, från 2003 till 2018. Med hjälp av data från samma tidsram implementeras även separata Granger Causality-tester för att testa sambandet mellan bruttoinskrivningsfrekvenser/Totala slutförandefrekvenser, på vissa nivåer utbildning och BNP-tillväxt. Intressant nog visar analysen inget Granger-kausalt samband mellan våra huvudsakliga intressevariabler (Total Education Expenditure och BNP-tillväxt). Resultat visar också att ingen av utbildningsvariablerna Granger orsakar BNP-tillväxt, om testet använder 1 tidstidsfördröjning och även om testet använder 3 tidsfördröjningar. Dessutom visar resultaten att oavsett om testet använder 1 tidstidsfördröjning eller 2 tidsfördröjningar, Granger orsakar BNP-tillväxt andelen av de totala offentliga utgifterna som är dedikerade till utbildning. Resultat för tester som använder 2 tidsfördröjningar visar också att den enda utbildningsvariabeln som Granger orsakar BNP-tillväxt är inskrivningsgraden på primärnivå, där BNP-tillväxten inte heller Granger orsakar någon utbildningsvariabel förutom procentandelen av de statliga utgifterna som är avsatta till utbildning. I fallet med testet med 3 tidsfördröjningar visar resultaten att BNP-tillväxt Granger orsakar endast en utbildningsvariabel, vilken är utgifter på gymnasienivå.

This study aims to investigate if there is any causal relationship between human rights and economic growth. The causality is tested in both directions, from human rights to economic growth and from economic growth to human rights, using a panel data Granger Causality test. The variable used to represent human rights is a human rights score and the variable used to represent economic growth is annual growth of real GDP per capita. Both of these variables are retrieved from Our World in Data. There is a total number of 81 countries included in this study with yearly observations from 1962 until 2017 on both variables. To achieve a greater depth the 81 countries were categorized into three different categories: low-income, middle-income and high-income countries. Previous studies and theories indicate that it is possible to expect a two-way causal relationship between economic growth and human rights. However, the results in this study indicate that there is no statistically significant causal relationship in any direction for any of the income categories.

Bakgrund och Problem: Aktiemarknaden påverkas både av inhemska och utländska faktorer. Därför är det av intresse att se vilka makroekonomiska variabler som påverkar den svenska aktiemarknaden. Anledningen till att Sverige har valts som den geografiska punkten är att det är av intresse att se hur ett litet land som Sverige, som har en öppen ekonomi påverkas av de utvalda makroekonomiska variablerna. Syfte: Syftet med uppsatsen är att med hjälp av information samt analys, studera hur de olika makroekonomiska variablerna påverkar den inhemska aktiemarknaden. Olika faktorer som påverkar aktiemarknaden kommer att lyftas fram för att i sin tur även se till de olika branscherna. Metod: Då data enbart består av hämtning av tidigare information fokuseras det enbart på sekundärdata i form av historiska siffror samt historiska undersökningar. De statistiska tester som tillämpas är Granger Causality test, Johansens Cointegration test, Impulse Response Function test, ADF test, KPSS test, Mulitpel regression. Slutsats: Med de resultat som presenterades i denna studie, skulle vi nog inte kunna säga att vi har ett svar över vilka aktier en investerare ska införskaffa. Dock skulle vi kunna poängtera att den potentiella investeraren bör ha dessa variabler i beaktning vid beslut. Genom att studera dessa variabler kan man få en känsla om vilket håll variablerna kommer att röra sig och på så sätt säga att de kan påverka aktieindexen. Att bara kolla på de makroekonomiska variabler som denna studie belyser räcker inte för att förstå hur aktieindex kommer att se ut i framtiden, men det är en bit på vägen till att förstå aktiemarknadens rörelse.

This study presents our attempt to examine the linkages and to investigate the linkage of stock price indexes among Taiwan, China and its major trading countries. Our empirical analysis employs daily data on stock price indexes over the period of January 2, 2000 to May 10, 2010. The total number of observations is about 2500. This study employ a sequence of time-series methodologies, including unit root test, cointegration test, vector error correction model, Granger causality test, Criterion, autocorrelation test, heteroscedasticity test, GARCH and Bi-GARCH. The findings of this study as follows. First, after first difference, every stock price indexes series all became stationary. Second, we found there has no long-run interrelationship among these stock markets. Third, we found that Taiwan¡¦s stock market exits leading role to China¡¦s stock market, but other countries¡¦ stock market lead Taiwan¡¦s stock market. For China, the stock market of United States, Japan, Taiwan and Hong Kong has a leading role to China¡¦s stock market. Only the rela-tionship between South Korea and China¡¦s stock market is independent. Forth, the result of autocorrelation test and ARCH test indicates that the influence of stock price indexes of major trading countries to Taiwan and China¡¦s stock price index has changed over time. Finally, the result of study indicates that every stock market can forecast its future trend by using its past stock data and investor can use the past stock data of stock market of major trading countries to forecast Taiwan and China¡¦s stock market.

自1970年代以來有許多研究指出，能源價格衝擊對於一個國家的總體經濟表現有顯著的影響。但對於能源價格究竟是以何種形式，以及透過什麼管道對總體經濟產生影響，卻沒有一致的看法。同時，經濟決策者對於能源價格變動的反應，經常因為有不確定性的存在而有延後反映的現象。本文利用台灣1981年到2009年的能源價格，建構數種對稱與不對稱之能源價格變動設定，以Granger因果關係檢定探討能源價格變動與台灣其他相關的總體經濟變數資料間的關係；並透過自我迴歸分配落後模型 (Autoregressive Distributed Lag Model, ARDL) 模型估計能源價格與台灣產出的長期關係。我們的實證結果顯示：能源價格，相較於台灣的總體經濟體系，具有外生性。能源價格成長率對產出與失業率沒有顯著的影響；但能源價格的波動程度對台灣產出成長率卻有顯著的負面影響。能源價格波動率與台灣實質產出具有長期均衡關係，而且能源價格波動將對台灣實質產出有負面影響。 / Since the 1970s, numerous studies have demonstrated that energy price impact can have a significant influence on a country’s macroeconomy. However, there is no consensus regarding in what form, or by which channel can energy price changes affect the macroeconomy. In addition, economic decision makers often respond to energy price changes with a time lag due to the existence of uncertainty. This paper constructs several indicators of symmetric and asymmetric energy price changes based on the energy prices in Taiwan for the period from 1981 to 2009. We employ the Granger’s causality test to examine the relationship between energy price changes and related macroeconomic variables; and utilize the autoregressive distributed lag model (ARDL) to estimate the long-run relationship between energy price volatility and Taiwan’s real GDP. Our empirical results show that energy price exhibits exogeneity relative to important macroeconomic variables; the energy price growth rate does not have significant impact on output and unemployment rate, while the energy price volatility has negative impact on Taiwan’s macroeconomy. There is long-run relationship between the energy price volatility and Taiwan’s real GDP. Furthermore, the energy price volatility do have negative impact on Taiwan’s real GDP.

台灣房地產景氣動向季報的發佈不但為台灣房地產市場該季景氣狀況提供一客觀參考依據，且對未來房地產市場景氣走向進行預測分析，提供房地產景氣相關資訊予社會各界參考。在對未來房地產景氣進行預測方面，是採用領先指標作為一參考標的，雖然領先指標就其特性而言為一預測未來景氣動向的參考資訊，但卻無法明確指出其所預測的期間為多長，本研究所欲探討的部分即在於使用房地產景氣綜合指標之領先指標於預測房地產景氣上可以預測幾季之後的房地產景氣狀況，並探討房地產景氣預測的準確度。另外對廠商景氣預測的部分進行一致性的檢視，再從而比較廠商景氣認知與同時、領先指標之間的關係。希望藉此能釐清房地產景氣季報內的訊息內涵。 本研究透過因果關係檢定，找出領先指標領先同時指標三季的關係，確定可以透過領先指標來預測三季之後的景氣變化情形。再利用平均絕對百分比誤差分析使用領先指標作為預測工具的準確度，經過計算求得平均絕對百分比誤差為4.57%，可以看出使用領先指標作為預測工具相當合適。在廠商本身預測景氣動向上，本研究發現廠商預期符合調適預期理論，且對未來的預期有較為樂觀的趨勢；經過本研究統計整理發現廠商對房地產景氣變動的認知與同時指標的變動之間的一致性並不理想，此有可能是因為市場上各項房地產資訊充斥，廠商並不全然以同時指標的變動來判斷房地產景氣的變動。惟經過前後期的比較，可以發現一致性的上升與不一致性的下降，表示兩者之間認知的一致性有逐漸提升的趨勢。 / The atmosphere of the real estate industry in Taiwan was upswing gradually in the past few decades, and its market information was definitely occupied an significant role and many people started to put their focus on it. In fact, the industry forecast which can be found from those seasonal report was a prediction only that is not accurate, i.e. those projections were based on the current market information only. Therefore, how to interpret and digest the number from those reports is the crucial issue for the reader to think and to consider. This study is trying to find out the time-lags between leading index and coincident index and the accuracy of the cycle forecasting system. The Granger causality test is widely used to examine the time-lags between the leading index and the coincident index. From the result of this study, we can found that there has a 3-season time-gap embedded in, and this is an obvious difference indeed. In addition, the forecasted index of the leading indicator i.e. The MAPE is in 4.57% sharp. Thus, we dare to judge that the result of this study is absolutely accurate with 100% confidence.

封閉型基金的掛牌買賣價格，與其投資標的淨資產價值（NAV, net asset value）間，總是存在一定程度的差距，且幾乎為10%~20%的折價現象，被視為財務學上的一種異常（anomaly）。早期研究學者們由經濟理性的角度解釋此種現象，認為是基金管理的績效表現、投資標的流動性或是稅制上的差異等等角度來解釋此一現象，但並沒有獲得一致的結論。 近期以來，有學者嘗試從行為財務學的角度，認為封閉型基金的折溢價現象及其幅度的變化，是由於投資人情緒（investor sentiment）的波動所造成。除了傳統的迴歸模式，更有不少學者以嚴謹的計量方式分析，例如財務時間序列的許多技巧。本研究即以時間序列之單根檢定（unit root test）、共整合現象檢定（co-integration test）及Granger因果關係檢定（Granger Causality test）等等方式，分析封閉型基金折溢價現象是否由投資人情緒所造成，及其兩者間是否有共整合現象。 雖然已有部分文獻探討類似議題，但跨國比較分析通常僅限於英、美兩國，且英、美兩國市場連動程度太高，可能影響分析結果的正確性；除此之外，樣本分析期間亦通常不超過十年。本研究以1991-2005年英國掛牌之封閉型基金為研究樣本，並包含投資標的為日本的封閉型基金，進行英國、日本之間的跨國性比較；不但有更足夠的樣本時間長度，亦能驗證是否不同跨國分析亦會有相同結論。 共整合現象檢定及Granger因果關係檢定大致支持行為財務學的角度。但英國、日本跨國比較的結果，似乎並不完全等同於前述英、美跨國比較的結果。建議後續可從掛牌國與投資標的區域連動程度較低的封閉型基金作為研究方向。 / The closed-end funds discounts have been an interesting phenomenon for a long period. Some theories based on economic rationale try to solve the puzzle but fail to get consistent conclusions. Recently some theories based on behavioral finance, such as the investor sentiment hypothesis, have been proposed to solve this puzzle. This study examines the investor sentiment hypothesis based on various time-series tests and finds some interesting results. Briefly, our conclusions are as follows: 1. The discounts can vary widely between funds and seem to be persistent in our sample period. 2. The local market indices are cointegrated with the domestic closed-end funds discounts and the information is flowed from the market to the closed-end funds, which support the investor sentiment hypothesis. 3. The causality relationship between the foreign closed-end funds and the local indices is not obvious. Based on this, the market segmentation hypothesis seems to hold in our sample, which indicates that investing in the foreign funds provide investors with the benefit of diversification. For future researches, we suggest that more the foreign funds should be included in the sample and the classification of the degree of investor sentiment and the categories of funds can also be improved.
